When revenue drops 20-40% in a quarter, most Australian SMEs measure their runway in weeks, not months. With the RBA cash rate sitting at 4.10%, the ATO holding more than $50 billion in collectable debt (two-thirds owed by small businesses), and Payday Super starting 1 July 2026, the financial buffer most owners thought they had has already shrunk. This is the 13-week playbook for what to do from the day the cash starts thinning.
Published: April 2026
A cash survival plan is a short-horizon, cash-basis financial plan built specifically for a business that has lost revenue and now needs to make sure outflows do not exceed inflows over a defined period. It is not a budget. It is not a forecast. It is a weekly schedule of every dollar coming in and every dollar going out for the next 13 weeks, paired with a list of decisions you will make in a defined order if cash gets tight.
The reason 13 weeks matters is simple: it is long enough to cover one full cycle of BAS, payroll, super, and most supplier payment terms, but short enough that the assumptions you make are still grounded in reality. Beyond 13 weeks the numbers become guesswork. Inside 13 weeks, they should be facts.
The owners who come through a revenue shock are not the ones with the deepest pockets. They are the ones who make decisions fastest. The single biggest predictor of whether a business survives a 30%+ revenue drop is the time between the drop becoming clear and the first cost-cutting decision being made. Owners who wait three weeks to act usually need to cut twice as deep. Owners who wait six weeks often run out of choices.
The reason most owners freeze is they are hoping the drop is temporary. Sometimes it is. Often it is not. The cost of acting early on a temporary drop is small (you reverse the cuts when revenue returns). The cost of acting late on a permanent drop is the business itself.
Before any decisions, you need three numbers in front of you. Pull them today.
Today's cash position. Total across every operating account, plus any undeposited customer funds and any genuinely available facility on an overdraft or business credit card. Do not include retainers held against future work. Do not include money sitting in offset accounts you have committed against personal mortgages.
A 13-week cash forecast with realistic revenue. Take your last three months of actual revenue and cut it by 20-30%. Use the lower number for the next 13 weeks. Map out every fixed outflow week by week: payroll, rent, super, BAS, loan repayments, key suppliers, software, ATO instalments. Then map expected inflows based on debtor ageing and conservative new sales assumptions. The output is a weekly closing cash position.
Your cliff date. This is the week your projected closing cash hits zero or breaches your overdraft limit. Mark it in red. Every decision from here is built around buying weeks before that date.
If you have never built a 13-week forecast, our cash flow forecast calculator is a starting point, and our guide on cash flow forecasting for Australian SMEs walks through the build in detail.
Pull a list of every recurring cost in the business: every Xero supplier, every direct debit, every contractor, every subscription. Sort each one into one of three buckets.
Bucket 1: Cut immediately. Subscriptions you can pause without business impact. Marketing spend that is not directly tied to a tracked sales pipeline. Discretionary contractors whose work can wait. Travel and entertainment. Office perks. Most owners find 8-15% of their cost base is in this bucket and most of it can be cut within a week.
Bucket 2: Renegotiate. Rent, software contracts, professional services retainers, key supplier payment terms, insurance premiums, lease arrangements. Ring every counterparty in this bucket within 14 days. The script is short: "We are in a tight period. I want to keep this relationship long term. Can we restructure the next three months?" You will be surprised how often the answer is yes, especially with software and rent.
Bucket 3: Protect at all costs. Key revenue-generating staff, customer-facing operations, anything that touches the ability to deliver and invoice. The temptation when cash is tight is to cut here first because the savings are biggest. Resist it. Cutting frontline before back-office is the most common fatal mistake in a cash crisis.
Cost cutting alone does not save businesses. Pulling cash forward does.
Call your top 10 customers personally in week 2. Not email. Phone. The conversation is short: "We are doing some work to clean up our cash position. Are there any pieces of work we can bring forward, any invoices you might be able to settle ahead of terms? Happy to offer a 2-3% discount for early payment." Roughly half will say no, but the half that say yes typically pull forward 3-6 weeks of revenue.
Identify and pause unprofitable customers. There is always one. The customer who pays late, demands the most service, and is on the lowest margin. In a survival period, they cost you cash twice: once in the gross margin gap, and again in the working capital they tie up. Pause new work for them. Tell them you are reviewing pricing.
Tighten new customer terms immediately. New work in this period takes a 30% deposit, full progress billing, or shorter payment terms. The cost of losing a deal because of terms is much smaller than the cost of funding new work through a cash crisis.
This is the section most owners skip until it is too late. Australian Fair Work obligations make people decisions slower and more expensive than in most other countries, which means the cost of delay compounds fast.
Three options exist when payroll is unsustainable:
Stand-down (Fair Work s524). Available only in narrow circumstances, generally where employees cannot usefully be employed because of a stoppage of work for which the employer cannot reasonably be held responsible. The bar is high. Most general revenue downturns do not qualify. Get specific advice before relying on this.
Reduced hours arrangement. A genuine agreement with employees to reduce hours and pay proportionally. Documented in writing, with the employee's consent. Often the most workable option, particularly with key staff who would prefer reduced hours over redundancy. The Fair Work Ombudsman covers the process and limits at fairwork.gov.au.
Redundancy. A formal redundancy where the role is genuinely no longer required. Pays out accrued entitlements plus redundancy pay scaled to length of service. Costly upfront, but final.
Delaying these decisions almost always costs more than making them. Every week you carry a role that should have been made redundant adds cost without buying any optionality. The owners who survive cash crises tend to make the call in week 3-4. The ones who do not survive tend to make it in week 8 or 9, by which point the redundancy payouts they could have funded have been spent on payroll.
For the broader cost picture, our employee cost calculator shows the full loaded cost per role.
By week 5 you have stabilised the cost base and pulled forward what revenue you can. The next lever is payment timing.
ATO payment arrangements. The ATO will agree to payment plans, but the process has tightened in 2025-26. Since 1 July 2025, GIC is no longer tax-deductible, which means carrying ATO debt is now significantly more expensive than most owners realise. The current GIC rate of around 10.65% per annum, on a non-deductible basis, costs the equivalent of roughly 15-16% on a deductible commercial loan. Apply for an arrangement early, with a clear repayment schedule and a 13-week forecast attached. The ATO is much more likely to approve a plan from a business that demonstrates it understands its own numbers. Detail on payment plan eligibility is at ato.gov.au.
Bank conversation. Do this early, with numbers, not late, with hope. Take your bank manager your 13-week forecast and the cost actions you have already taken. Ask for an interest-only period, a temporary increase in overdraft, or a working capital facility. Banks are far more willing to work with businesses who present a clear plan than with businesses who go quiet then ask for emergency help six weeks later.
Supplier extensions. Send a personal email to your top 10 suppliers requesting an extension of terms by 14-30 days for a defined period. Most will agree if you have a track record of paying on time. The framing matters: "We are working through a tight period and I want to make sure we keep paying you reliably. Can we move to net 60 for the next three months and return to net 30 from October?"
By week 9 you should know whether the revenue drop was temporary or structural. If revenue is recovering, start cautiously rebuilding. If it has stabilised at the lower level, lock in the cost structure permanently.
This is the period to bake in the lessons. Three things should change permanently:
A minimum cash buffer policy. Most SMEs that survive a cash crisis emerge committing to hold 2-3 months of operating expenses in reserve at all times.
Tightened customer terms. Net 30 with deposits, automated reminders, and direct debit as default for new customers.
Customer concentration limits. No single customer should represent more than 20-25% of revenue. If one already does, the recovery period is when you start diversifying.
Our article on why cash feels tight when profits look fine covers the structural patterns most businesses miss when they rebuild.
After 90 days the businesses that have survived have usually avoided all five of these. The ones that have not survived have typically made three or more.
Hoping the drop is temporary. Acting on the assumption it will reverse, cutting too little, and discovering in week 8 that the runway is gone.
Cutting too late or too little. The savings from a cost cut compound across every remaining week of the crisis. A $20k/month cut made in week 2 saves $240k. The same cut made in week 8 saves $80k.
Avoiding the bank or ATO. Both will engage constructively if you come early with a plan. Both will lose patience if you go silent. The ATO in particular is now using the full range of collection tools including Director Penalty Notices, garnishee notices, and disclosure of business tax debts to credit bureaus.
Cutting frontline staff before back-office. Cutting the people who generate revenue to save the people who process it. Common, fatal, almost always wrong.
Going quiet with the team. Staff know when something is wrong. Silence makes them assume the worst, and the best ones leave. Tell them what is happening, what you are doing about it, and what you need from them.
Most owners trying to navigate a 90-day cash crisis are doing it on top of running the business. The cognitive load is significant: forecasting, scenario modelling, ATO and bank conversations, customer renegotiations, and the people decisions, all at once. A fractional CFO typically takes 2-3 of those workstreams off the owner's desk and brings senior experience to each.
Specific triggers to consider bringing in fractional CFO support:
You do not have a current 13-week forecast or you do not trust the one you have. You are about to have an ATO or bank conversation and have not done one before. You have customer concentration above 30% and one of those customers is at risk. You are facing redundancy decisions and have not run them before. You are working more than 60 hours a week and finance work is being squeezed out.
The first 7 days of fractional CFO engagement in a crisis usually involve: building or rebuilding the 13-week forecast, mapping the three cost buckets, scripting the customer and supplier conversations, and producing a one-page summary you can take to the bank.
How quickly should I cut costs after a revenue drop?
Inside two weeks for Bucket 1 (immediate cuts). Inside four weeks for Bucket 2 (renegotiations). The compounding effect of acting fast is the single biggest lever in a cash crisis. A $15k/month cut made in week 2 saves you $195k across 13 weeks. The same cut in week 7 saves $90k.
Can the ATO refuse a payment plan?
Yes. The ATO has tightened its approach since 2024 and now expects evidence that the business is viable, that the plan is achievable, and that the owner is engaged. Plans are more likely to be approved when accompanied by a current 13-week forecast and where existing lodgements are up to date. Plans are more likely to be refused where lodgements are overdue, where prior plans have defaulted, or where the business has no clear path back to compliance.
What is a Director Penalty Notice and when can I receive one?
A Director Penalty Notice (DPN) is an ATO notice that makes a company director personally liable for unpaid PAYG, super, or GST. The ATO can issue a non-lockdown DPN, which gives 21 days to act, or a lockdown DPN, where personal liability is automatic if reporting obligations are more than 3 months overdue. Keeping BAS, super, and PAYG lodgements current is the single most important protection against personal liability, even if the underlying tax cannot be paid on time.
When should I consider voluntary administration or small business restructuring?
These are formal insolvency processes and require specific advice from a registered liquidator or restructuring practitioner. As a general guide, owners should be having these conversations when the 13-week forecast shows insolvency within 8-12 weeks despite full cost-cutting actions. Small Business Restructuring (SBR) under Part 5.3B of the Corporations Act has been used increasingly in 2025-26 to compromise unsecured debt including ATO debt while keeping directors in control.
Can I stand down employees without pay during a revenue downturn?
Generally no. The Fair Work Act allows stand-down only in limited circumstances where work cannot usefully be performed because of a stoppage for which the employer is not responsible. A general revenue decline does not usually qualify. Employees can agree to reduced hours arrangements, take leave, or in some cases agree to a temporary pay reduction, but each requires written consent.
Do I need to tell my customers we are going through a cash flow problem?
No, and you should not. Customers do not need to know your cash position. They do need to know if there will be any change to service levels, delivery timelines, or contact points. Keep the conversation focused on what they will experience, not on internal cash dynamics.
How do I know if I should keep cutting or stop?
The forecast tells you. If the 13-week forecast shows positive closing cash every week with a buffer of at least 2-3 weeks of operating costs, the cuts are sufficient. If any week is forecast to go negative, more action is required. The forecast is updated weekly, with actuals replacing assumptions as they land.
